1) The square (squarish) vase. There are 4 STL files. Which one did you use? Normally I would recommend one of the first 2 and tell you to uncheck the "solid infill top". Is this what you did? Be aware that if you do this there will be ZERO retraction because Cura doesn't retract *inside* prints. So you if you want retraction to work, instead use "thickwall" or "3mm wall".

2) You shouldn't have this issue with this other "stratum" vase. In Cura, after it slices, look at the vase in layer view. Layer view shows a blue line for non-extruding moves but for retraction it additionally shows a short vertical line segment. Look for those to see if Cura is in fact doing retraction. It probably *is* doing retraction but if not, show us a screen shot of Cura where you think it should be retracting yet it isn't.

3) Even with retraction occurring, you can still get strining. Try printing MUCH slower. Try 1/3 the speed you are printing now. Also try as low a temp as you can go. Maybe 190C. Or maybe that is too cold for your filament. Both slowing down and cooler temperatures -- these both reduce stringing -- see first photo here:

@jamboy - that picture is fuzzy but I can clearly see at least one retraction indicator - it's those short blue lines that go straight up vertically. Could you give a second screenshot but at a better angle so we can see the vertical lines? The one around "1 o'clock" looks good and I think there is one around "9 O'Clock" that also looks good. It's very hard to tell in this image.

It looks like maybe it is only retracting on *some* of the lines and not others but I'm not sure mostly because of the angle. Do you have "combing" enabled? Can you just also save your profile and post the entire ini file as text? But more importantly post another screenshot with a better angle.

It is possible to print with UM1 settings (You'll get a warning that the settings in the machine will be ignored)

And I think it's related to the "minimal extrusion amount", this setting is added to prevent a lot of retraction on a small piece of filament, but it might act a bit different on the UM1 then the UM2 settings.

Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
